The Liaoning ship and the Shandong ship are both STOBAR aircraft carriers that take off by ski jump. After all, the launch efficiency of the carrier-based fighter cannot be compared with that of the CATOBAR aircraft carrier. Therefore, Chinese military fans always hope that the Shandong ship and the Liaoning ship will be modernized. It is possible to dismantle the ski jump deck and install or even rebuild the angled deck , and install two or three electromagnetic catapults . thereby improving combat effectiveness. This is called leveling the Shandong and Liaoning ships.
The 75 amphibious assault ship has the most rectangular flight deck in the world, and a bow bulkhead with a thickness of two cabins, so that it is 0.75 square meters like a brick. This design that is so simple that it makes people cry always makes people feel that something is missing, so when the 075 was launched, there was a cartoon about using an extra-large screwdriver to fix the ski jump deck to the bow of the 075 ship. This is called bending 075.
I never expected that two years later, this comic would actually be updated... I don’t know which PS master concocted the PS picture of the 075 ski jump deck version, and the big package is a whole CG picture... So let’s put it aside for now The question of whether our country has vertical takeoff and landing fighter , assuming we do, or China and Russia have jointly resurrected YAK-143 or even YAK-201 (the stealth improved version of YAK-141) has also solved the problem of deck heat-resistant coating question, and decided to carry a carrier-based vertical take-off and landing fighter on the Type 075 amphibious assault ship. So how will the Type 075 install a ski jump deck?
YAK-201
If 075 is really equipped with a ski jump, it will not use a ski jump deck with the same width as the bow.
Many ideas about 075 adding a ski jump deck are to add a ski jump to the bow of 075. The ski-jump deck module is of equal width, and the ski-jump deck module greatly protrudes from the bow of the ship (ignoring the ecstatic slotted screw for the moment). After rational adjustments, this idea is close to adding a Shandong on the bow of the 075. , Liaoning, and Kuznetsov have the same extended full-width ski jump deck. Therefore, the 1143.5 bow CTRLX + the 075 drawn by myself on the plate + dodge is equal to =
is almost the same thing
is almost the same thing as the picture above. After all, the reserve buoyancy of the front part is limited, so the ski jump deck naturally cannot float too much. When designing a ski jump deck with a limited length, it is necessary to avoid the inclination angle changing too quickly, so part of the take-off area deck needs to be reshaped.
is almost the same thing as
but this design is obviously unreasonable. 1143.42, Kuznetsov, Varyag, Garibaldi, Ulyanovsk , Chakrina Lubet, Liaoning, Shandong, Vikramaditya, Vikrant The reason why the ski jump deck is designed to be as wide as the bow of the ship is because all the above-mentioned ships adopt an inclined take-off area design.
This means that when the carrier-based aircraft is taxiing to take off, since the carrier-based aircraft's taxiing direction is inconsistent with the aircraft carrier's forward direction, the carrier-based aircraft will encounter a force that causes the carrier-based aircraft to deviate from its original forward direction. In order to ensure that the carrier-based aircraft can take off smoothly from the ski-jump deck instead of falling from the other end, it is necessary to continuously fine-tune the tail during take-off so that the sliding direction of the carrier-based aircraft is always aligned with the ski-jump indicator line. Even so, When encountering a sudden crosswind, the carrier-based aircraft will still slide to both sides of the ski jump deck, so the ski jump deck needs to be designed wider. If the design is too narrow, the carrier-based aircraft will easily fall.
For an aircraft carrier, this shortcoming is nothing. After all, if you tilt the take-off indicator line, you can plan an additional take-off point. Except for the pilot who loses, the other parties involved will make a profit.
But for the amphibious assault ship , it is really unnecessary... Amphibious assault ships generally have a very regular flight deck. The unobstructed left deck is the take-off and landing area, and there is a ship island in the middle on the right side. The deck is the parking area. Regional divisions do not infringe the well water.
And when the carrier-based aircraft of the amphibious assault ship/ light aircraft carrier take off (except for the Garibaldi and the small Thai aircraft carrier), they stay on the left deck the entire process and will not go to the right deck.The take-off line is also parallel to the central axis of the deck. The complexity of the forces on the carrier-based aircraft during taxiing is far lower than the complexity of the forces on the inclined take-off line.
Therefore, it is not necessary for a flat-deck surface ship whose carrier-based aircraft take-off area line is parallel to the longitudinal axis of the deck to have a ski-jump deck with the same width as the bow. A half-width ski-jump deck can be used.
Britain's Invincible-class light aircraft carrier, Queen Elizabeth-class aircraft carrier , HMS Arenas light aircraft carrier; Italy's Cavour-class light aircraft carrier, HMS Trieste amphibious assault ship; USS Vikrant light aircraft carrier, HMS Hu Ancarlos I-class strategic delivery ship, USS Anadolu light aircraft carrier, Canberra-class amphibious assault ship . Invariably, a half-width ski-jump deck with a width accounting for about half of the bow is adopted.
The half-width ski jump deck can be divided into two situations in design. The first one is the Juan Carlos I-class strategic projection type ski jump deck that is designed to be integrated with the hull. The other is the island-type ski jump deck independent of the deck used by Britain, India and Italy.
The ski jump deck is extended and designed to be integrated with the hull, which can extend the bow of the ship to the maximum extent. The problem is that the 075 does not look like the configuration where the ski jump deck was considered at the beginning of the design. In other words, the most suitable arrangement when adding a ski jump deck to the 075 is to arrange an island-type ski jump deck. After all, the installation of this kind of ski jump deck is relatively easy, and the corresponding ski jump deck module can even be manufactured in advance and installed when needed. (This is true for Trieste and the Queen)
Of course, the ski jump deck arranged in this way needs to occupy about one helicopter take-off point, but the 075 has 6 take-off points, sacrificing one helicopter take-off point for vertical take-off and landing. The fighter's ability to ski-jump off is still worthwhile.
The problem is that 075 wants to install a ski jump deck. At this stage, we can only think about it. After all, the vertical take-off and landing fighter aircraft has not even started to scratch the surface, let alone that one.
